WebAug 17, 2015 · Meaning COMSOL decides which boundary is the source/Destination and also defines the coordinate-dependency like: For a antiperiodic case where the boundaries are symmetric to the y- and z-axis, Variable (x,y,z) on Boundary1 = - Variable (-x,y,z) on Boundary2 So far, this has never been a Problem for me. WebWhen creating the periodic boundaries, I disable “Automatic Compute Offset” and input the offset manually, as the offset is the same for all angles of attack. However, when I close the interface setup window and re-open it, “Automatic Compute Offset” is enabled again…. Problem 2: This is causing issues in the parametric study.

WebNov 26, 2009 · It sounds like you want floquet periodic boundary conditions (PBCs) for the sides from which the plane wave starts. For example, if you want a plane wave going only in the x direction, select floquet PBCs for the sides of the cube on the x … WebPeriodic Condition The Periodic Condition node adds a periodic boundary condition. This periodicity can be continuous (the default) so that u(x0) = u(x1) or antiperiodic so that u(x0) = −u(x1) and can control to which dependent variables the periodic condition applies.
